CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit under Title 35, U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. No. 60/298,756, entitled FLOOR-TO-CEILING WALL PANEL SYSTEM, filed on Jun. 15, 2001.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to office partition systems, and more particularly, to a movable office panel system including panels which extend between the floor and the ceiling of an office space.

[0004] 2. Description of the Related Art

[0005] Floor-to-ceiling office panel systems typically include individual panel units associated with the existing permanent walls of an office space, the panel units extending between the floor and the ceiling of the office space and dividing same into multiple rooms, such as individual offices, conference rooms, and the like. Typically, such panel systems are custom designed and manufactured for a particular office space according to a predetermined office floor plan, and are installed in a relatively permanent manner within the office space. Therefore, such panel systems tend to be rather costly and difficult to install, and often cannot be relocated if modifications to the office floor plan are desired.

[0006] For example, existing panel systems typically include heavy, rigid frames made from frame members which are cut to a pre-measured length and permanently welded to one another. Additionally, the panel frames typically include a large number of additional components for attaching the panel frames to one another, and also for attaching the panel frames to the floor and to the ceiling of the office space. Typically, such components are specifically designed for a particular use, or for a specific type of panel-to-panel connection, such as a T-, L-, or X-type connection, and may only be used for such specific connection or other specialized use. The large amount of such parts increases both the cost and the difficulty of manufacturing and installing existing floor-to-ceiling panel systems.

[0007] As a result of the complexity of the design of existing floor-to-ceiling wall panel systems, the installation, modification, and removal of same typically require trained and experienced work crews, such that modifications to the configuration of the panel system, to the extent that any such modifications are allowed by the design of the system, cannot easily be made.

[0008] What is needed is a floor-to-ceiling wall panel system which is an improvement over the foregoing; specifically, a floor-to-ceiling wall panel system which includes a minimal number of components is easy to install and easy to modify after installation, and which can accommodate existing modular office components.

SUMMARY OF THE INVENTION

[0009] The present invention provides a floor-to-ceiling wall panel system in which each panel includes a universal frame adjustably attached to a floor track member which rests on a floor surface, the frame additionally including a jack post assembly for releasable connection to a ceiling track fastened to a ceiling. The panel system includes a number of multi-functional components, thereby reducing the total number of components in the panel system and facilitating easier installation of the panel system, as well as easier modification of the panel system once installed.

[0010] For example, a single track member may serve as both the floor track and the ceiling track. Also, a single type of spring clip may be used to attach several components to the panel frames, such as opaque panel skins and window panels, for example. Also, the spring clips are used to attach trim pieces to the floor and ceiling tracks which mask the adjustable connections of the panel frames to the floor and ceiling. Further uses of the spring clips are described in detail below.

[0011] The frame includes vertical frame members each formed by a pair of C-shaped vertical sub-frame members which are attached to one another in a back-to-back manner to form a vertical frame member having an I-shaped cross section for structural rigidity. Corner blocks are captured in the upper and lower ends of the vertical frame members, and serve as attachment points for horizontal frame members to the vertical frame members. The corner blocks may be selectively configured in a support block mode for attachment to a lower horizontal frame member to provide a vertically adjustable connection between the frame and the floor track, or the corner blocks may be configured in a jack post block mode for attachment to an upper horizontal frame member to provide an adjustable, releasable connection between the frame and the ceiling track.

[0012] A single panel connecting bracket may be attached to the corner blocks of adjacent panels to connect same in and end-to-end relationship, as well as to connect additional panels thereto to form building module L-type connections, T-type connections, or X-type connections between multiple panels. Further, a corner post is provided, which may also be used as desired to provide the foregoing types of connections in a furniture module mode. In an alternative embodiment, cam locks are provided to attach panels together to form the above connections.

[0013] An intermediate horizontal frame member may be attached to the vertical frame members at horizontal levels with respect thereto which may vary in increments up to one-eighth of an inch. Electrical and or data wiring harness assemblies may be attached to the floor track to provide electrical and data service throughout the lower region of panel system, or alternatively, may be attached to an intermediate frame member to provide electrical and data service throughout the panel system at any mid-height level. Existing mounting tracks may be secured to the horizontal frame members, or alternatively, to an intermediate frame member, to provide an attachment interface for existing modular furniture components, such as work surfaces, cabinets, shelves, and the like.

[0014] In this manner, the mounting tracks, when attached to the intermediate frame members, may be disposed at virtually any vertical level with respect to the surrounding panel frame. The foregoing construction allows the mounting tracks of the panels in the panel system to be aligned with identical mounting tracks which are mounted to permanent walls of an interior office space to provide aesthetic, visual continuity between the panel system and the permanent walls of the office space.

[0015] Advantageously, the present floor-to-ceiling wall panel system includes a universal frame which is easily assembled to any desired dimension, and which is configured to accept opaque panels skins, window panels, or any desired combination thereof.

[0016] In one form thereof, the present invention provides a partition system for partitioning a work space, including a frame, the frame including at least one vertical frame member having a series of substantially vertically aligned first holes therein, and at least one horizontal frame member; at least one bracket having a first portion attached to the horizontal frame member and a second portion having at least one second hole therein adapted to align with at least one of the first holes in the vertical frame member; at least one fastening element inserted through the first and second holes to secure the horizontal frame member to the vertical frame member; and a track member supported horizontally on the horizontal frame member, the track member configured for attachment of modular furniture components thereto.

[0017] In another form thereof, the present invention provides the combination of a permanent wall having a first track member horizontally supported thereon, the first track member configured for attachment of a modular furniture component thereto; and a partition system frame having at least one horizontal frame member, and a second track member horizontally supported on the at least one horizontal frame member, the second track member configured for attachment of a modular furniture component thereto; wherein the partition system frame is disposed adjacent the permanent wall, and wherein the first track member of the permanent wall is horizontally aligned with the second track member of the partition system frame.

[0018] In a further form thereof, the present invention provides a partition system for partitioning a work space, including a frame including at least one vertical frame member and at least one horizontal frame member; a least one spring clip removably attached to one of the horizontal and the vertical frame members, the spring clip including a spring body portion with a pair of leg portions extending therefrom, one of the leg portions and the spring body portion engaging the one frame member; and a partition system component including a receiving element to which is attached the other of the leg portions and the spring body portion of the spring clip, the spring clip thereby attaching the partition system component to the frame member.

[0019] In a further form thereof, the present invention provides a partition system for partitioning a work space, including a floor track; a ceiling track; a frame disposed intermediate the floor track and the ceiling track, including upper and lower horizontal frame members, and at least one vertical frame member having an upper portion and a lower portion; first and second corner blocks, the first, corner block attached to the upper portion of the vertical frame member and connecting the upper horizontal frame member thereto, the second corner block attached to the lower portion of the vertical frame member and connecting the lower horizontal frame member thereto; the first corner block further including a first engagement assembly connecting the frame to the ceiling track; and the second corner block further including a second engagement assembly connecting the frame to the floor track.

DETAILED DESCRIPTION

[0116] Referring to FIG. 1, office space 40 is shown, including floor-to-ceiling wall panel system 42. Floor-to-ceiling wall panel system 42 includes a plurality of individual partition panels 44 which may attached to one another, for example, by end-to-end connections 46, T-type connections 48 a, 48 b, L-type connections 50 a, 50 b, and X-type connections (not shown). Panels 44 may also be attached to permanent walls 43 or permanent columns 45 of the building within which office space 40 is disposed, wherein panels extend from floor 52 to ceiling 54 of office space 40 to define individual partitioned office spaces 41 a, 41 b, 41 c, which may be offices, work stations, conference rooms, reception rooms, and common areas, for example. Further, as shown in FIG. 1, panels 44 may include opaque panel skins 226, window panels 236, or any desired combination of the foregoing, as described further below.

[0117] More particularly, the individual partition panels 44 are attached to one another, for example, by end-to-end connections 46, building module T-type connections 48 a, furniture module T-type connections 48 b, building module L-type connections 50 a, furniture module L-type connections 50 b, and furniture and module or building module X-type connections (not shown), each of which is described further below. Generally, building module connections between panels 44 allow panels 44 to follow the existing ceiling grid structure within a building, and do not employ corner posts at the L-, T-, or X-type connections between panels 44, while furniture module connections may or may not follow the existing ceiling grid structure within a building, and employ corner posts at the L-, T-, or X-type connections between panels 44. Office space 41 c additionally includes a pair of 135 degree panel-to-panel connections 51, as also described further below.

[0118] Each panel 44 includes universal frame 56, shown in FIGS. 2A through 3C, which generally includes vertical frame members 58 attached to horizontal frame members 60, as well as one or more intermediate horizontal frame members 144 if desired, as shown in FIGS. 9A and 9E, and described below. Vertical and horizontal frame members 58, 60 may be cut to any desired length, such as at one fourth inch increments, for example, in order to vary the overall dimensions of frame 56, and are attached to one another at corner blocks 62 a or 62 b, as described below. As shown in FIGS. 2A and 2B, frame 56 includes corner blocks 62 a according to a first embodiment and, as shown in FIGS. 3A-3C, frame 56 includes corner blocks 62 b according to a second embodiment. Additionally, floor track 64, which is disposed along floor 52, is attached to frame 56. As shown in FIG. 8, frame 56 is also detachably connected to ceiling track 66 fastened to ceiling 54, as described below.

[0119] Referring to FIGS. 4A-4E, vertical frame members 58 have a substantially I-shaped cross section, defined by a pair of substantially C-shaped sub-frame members 68 (one of which is shown individually in FIG. 4B) which may be formed from bent, roll-formed steel, for example. Sub-frame members 68 each include base wall 70 with a pair of parallel side walls 72 extending therefrom, and which are bent inwardly at 74 adjacent the ends thereof. A vertical series of slots 80 are formed in side walls 72 of sub-frame members 68 along bend 74, into which may be inserted suitable hanging hardware for hanging modular furniture components, such as a work surface, cabinet, or shelf, for example, from frame 56 of panel 44. Base walls 70 of sub-frame members 68 additionally include two vertical series of holes 76 and windows 78 therein. Sub-frame members 68 are attached to one another in a suitable manner, such as by welding or by fasteners, for example, or by die-punching a tox 71 (FIGS. 4A and 4D) in at least two locations along abutting base walls 70 of sub-frame members 68 to bind same together. Regardless of how sub-frame members 68 are attached to one another, respective base walls 70 of sub-frame members 68 abut one another with respective side walls 72 thereof extending away from one another to define vertical frame member 58, wherein corresponding holes 76 and windows 78 of sub-frame members 68 are aligned. The I-shaped cross section of vertical frame members 58, defined by sub-frame members 68, provides structural rigidity to vertical frame members 58.

[0120] Horizontal frame member 60, shown in FIGS. 2A through 3C and 7A, may be formed of an elongated piece of extruded aluminum, for example, and, referring particularly to FIG. 7A, generally includes central web portion 82 and a pair of parallel side portions 84 defining a substantially H-shaped cross section. Central web portion 82 includes a pair of fastening embossments 86 formed on one side thereof, and a pair of tongues 88 extending from an opposite side thereof which depend toward each other to define channel 90. Other than fastening embossments 86 and tongues 88, central web portion 82 defines a horizontal axis of symmetry through horizontal frame member 60, allowing horizontal frame member 60 to be selectively rotationally oriented such that fastening embossments 86 are disposed on either an upper or lower side of central web portion 82, as described further below. Side portions 84 are shaped to define first channel 92 and second channels 94 disposed above and below first channel 92, respectively, wherein each of the foregoing first and second channels 92, 94 open generally outwardly of horizontal rail member 60 and frame 56. A series of protrusions 96 are defined at the openings of first and second channels 92, 94. First channel 92, as described further below, is adapted to receive a threaded fastener therein for attaching a mounting track to frame 56.

[0121] As shown in FIG. 4F, corner blocks 62 b (or 62 a) are received in each of the upper and lower portions of vertical frame members 58, and specifically, are captured within the space defined within one of the C-shaped vertical sub-frame members 68 thereof. Referring additionally to FIG. 3C, corner blocks 62 a. 62 b include two horizontal pairs of holes 98 a, 98 b therein. Threaded fasteners 99 extend through holes 76 in vertical frame members 58, holes 98 a, 98 b in corner blocks 62 a, 62 b and into fastening embossments 86 of horizontal frame members 60 to secure horizontal frame members 60 to vertical frame members 58 to define frame 56. An upper horizontal frame member 60 may be aligned with fastening embossments 86 disposed above central web portion 82 thereof, with the fasteners extending through upper horizontal pair of holes 98 a in corner blocks 62 a, 62 b, and a lower horizontal frame member 60 may be aligned with fastening embossments 86 disposed below central web portion 82 thereof, with fasteners extending through lower horizontal pair of holes 98 b in corner blocks 62 a, 62 b. Alternatively, the foregoing orientation of horizontal frame member 60 may be reversed. Additionally, the ends of side portions 84 of horizontal frame members 60 abut plates 100 a, 100 b of corner blocks 62 a. 62 b to align horizontal frame members 60 in a square orientation with respect to vertical frame members 58, thereby providing an installation guide for connecting horizontal and vertical frame members 60, 58 in a square orientation with respect to one another.

A pair of bolts 124 are respectively slidably disposed through second bores 110 of jack post block 104 a. Ends 126 of bolts 124 each threadably engage jack plate 128 a, and nuts 130 are threaded onto bolts 124. Springs 132 are respectively disposed around bolts 124, and the ends of same are trapped between block portion 106 of jack post block 104 a and nuts 130 on bolts 124 to thereby bias bolts 124 outwardly of jack post block 104 a. Jack plate 128 a includes tongue 134 depending therefrom which engages lip 136 of plate 100 a to lock jack post assembly 122 a in a retracted position, with jack plate 128 a disposed adjacent jack post block 106. Referring also to FIG. 8 upon release of tongue 134 of jack plate 128 a from lip 136 of plate 100 a, springs 132 bias bolts 124 and jack plate 128 a of jack post assembly 122 a upwardly to engage jack plate 128 a with ceiling track 66 to secure frame 56 of panel 44 thereto. Specifically, protruding portions 138 of jack plate 128 a seat within recesses 140 (FIGS. 7B, 8) of ceiling track 66 to prevent tilting movement of frame 56 out of a vertical plane. Thereafter, nuts 130 may be threaded downwardly around bolts 124 and into abutment with the upper surface of plate 100 a to prevent retraction of jack post assembly 122 a and to thereby releaseably lock jack post assembly 122 a and frame 56 of panel 44 into engagement with ceiling track 66.

[0127] A second embodiment of a jack post block is shown in FIGS. 5C-5E. Jack post block 104 a includes jack post assembly 122 b. Similar to jack post assembly 122 a, jack post assembly 122 b includes a pair of bolts 124 respectively slidably disposed through second bores 110 of jack post block 104 b, wherein ends 126 of bolts 124 each threadably engage jack plate 128 b. Springs 132 are respectively disposed around bolts 124, and the ends of same are trapped between block portion 100 b of jack post block 104 b jack plate 128 b to thereby bias jack plate 128 b and bolts 124 outwardly of jack post block 104 b. Jack plate 128 b includes apertures 119, 121 therein for receiving jack post retainer spring 113, wherein arms 115 of jack post retainer spring 113 are received within aperture 119, and spring leg 117 of jack post retainer spring 113 is disposed within aperture 121. Additionally, jack post assembly 122 b includes jack post lock plate 123, having slots 125 therein.

[0128] Jack post assembly 122 b is shown in a retracted position in FIG. 5D, such as when same is in a shipment or pre-installation position. In this position, engagement of spring leg 117 of jack post retainer spring 113 with the edge of plate 100 b of jack post block 104 b retains jack plate 128 b in a retracted position, with springs 132 under compression between jack plate 128 b and plate 100 b. Additionally, jack post lock plate 123 is disposed between jack plate 128 b and the upper ends of springs 132, wherein bolts 124 are received within slots 125 of jack post lock plate 123. A downward force upon jack plate 128 b releases spring leg 117 of jack post retainer spring 113 from the edge of plate 100 b, allowing springs 132 to bias bolts 124 and jack plate 128 b upwardly to engage jack plate 128 b with ceiling track 66 in the same manner as described above with respect to jack post block 104 a and jack post assembly 122 a (FIG. 8). The downward force upon jack plate 128 b for releasing same may be exerted by an installer using a pole (not shown), for example, such that the installer may conveniently release jack plate 128 b from a standing position therebelow to set the initial engagement between jack plate 128 b and ceiling track 66. After jack plate 128 b is engaged with ceiling track 66, jack post lock plate 123 is removed from bolts 124, and relocated to the position showing FIG. 5E, wherein the threads of bolt 124 and portions of springs 132 are captured by slots 125 of jack post lock plate 123 to secure jack plate 128 b and bolts 124 in the extended position shown in FIG. 5E.

[0129] Floor and ceiling tracks 64, 66, shown in FIG. 7B, may be formed of identical pieces of extruded aluminum, for example, thereby reducing the number of components associated with floor-to-ceiling panel system 42. Additionally, referring to FIGS. 2A through 3C and 7B, floor track 64 includes curved edge 142, which allows panel frame 56 to slide or skid across a floor surface when pushed by an installer to any desired location before engaging jack post assemblies 122 a or 122 b are engaged with ceiling track 66 to secure panel frame 56 thereto, as described above. Additionally, screws (not shown) may be threaded through floor track 64 to grip carpet on floor 52, or alternatively, such screws may be directly threaded into a permanent floor surface to attach floor track 64 thereto for securing panel frame 56 to a floor surface.

[0130] Additionally, referring to FIG. 9A, panel frame 56 may include one or more intermediate horizontal frame members 144, which may be formed of pieces of extruded aluminum identical to horizontal frame members 60. L-shaped brackets 146, according to a first embodiment, connect intermediate horizontal frame members 144 to vertical frame members 58, and include first flange 148 slidably disposed within the channel 90 of intermediate horizontal frame member 144 which is defined by tongues 88, and shown in FIG. 7A. Second flange 150 of intermediate brackets 146 connect to vertical frame members 58 via fasteners (not shown) disposed through holes 152 in intermediate bracket 146 and through holes 76 in vertical frame members 58. Slots 154 in second flange 150 accommodate the ends of tongues 88 of intermediate horizontal frame member 144.

[0131] Holes 76 in vertical frame members 58 may be disposed therealong at one-half inch center-to-center intervals, thereby allowing intermediate horizontal frame members 144 to be located at any horizontal level corresponding to one-half inch vertical intervals with respect to frame 56. Additionally, intermediate horizontal frame member 144 may be selectively mounted to vertical frame members 58 in one of two rotational orientations, with fastening embossments 86 disposed on either the upper or lower side of central web portion 82, which orientations vary the vertical position of intermediate horizontal frame member 144 by one-fourth of an inch relative to vertical frame members 58. Therefore, the one-half inch spacing between holes 76 in vertical frame members 58, as well as the selective rotational orientation of intermediate horizontal frame member 144, allow intermediate horizontal frame member 144 to be located at any horizontal level corresponding to one-fourth inch vertical intervals with respect to frame 56. Additionally, intermediate bracket 146 may be provided with multiple sets of holes 152 for selective alignment with holes 76 of vertical frame members 58 and which, when combined with the foregoing further adjustment provided by the selective rotational orientation of intermediate horizontal frame member 144, allows intermediate horizontal frame member 144 to be located at any desired one-eighth inch vertical interval along vertical frame members 58 of frame 56.

[0132] A method of connecting intermediate horizontal frame members 144 to vertical frame members 58 according to a second embodiment is shown in FIGS. 9B-91. Referring first to FIG. 9B, L-shaped brackets 147, according to a second embodiment, include first flange 149 and second flange 151 extending at right angles from one another. First flange 149 includes a first set of four holes 153 and center holes 155. Second flange 151 includes a second set of four holes 157, center holes 159, and 1350 connection holes 161. The function of 135° connection holes 161 will be explained below. Either first or second flanges 149, 151 of L-shaped brackets 147 may be inserted into the channel 90 of intermediate horizontal frame member 144 which is defined by tongues 88, and shown in FIG. 7A. However, in the embodiment shown in FIGS. 9B-9I, the orientation of intermediate horizontal frame member 144 need not change to effect connection of intermediate horizontal frame member 144 at one-eighth inch intervals along vertical frame members 58 intermediate horizontal frame member 144 may be oriented such that channel 90 thereof is disposed below fastening embossments 86 for all such connections.

[0133] As shown in FIGS. 9C and 9D, fasteners 99A are inserted through central web portion 82 of intermediate horizontal frame member 144 and into either center holes 155 or 159 of first flange 149 or second flange 151, respectively, of L-shaped brackets 147 to secure L-shaped brackets 147 to intermediate horizontal frame member 144. Thereafter, referring to FIG. 9D, further fasteners 99 are inserted through a pair of first or second sets 153, 157 of holes in first or second flanges 149, 151 of L-shaped brackets 147 to secure same to vertical frame members 58, as described below. For example, in FIG. 9E, an intermediate horizontal frame member 144 is shown attached to vertical frame members 58 of panel frame 56 at a mid-height location.

[0134] Referring to FIGS. 9F-91, the manner in which intermediate horizontal frame members 144 may be attached to vertical frame members 58 of panel frame 56 is shown. In FIG. 9F, second flange 151 of L-shaped bracket 147 is attached to intermediate horizontal frame member 144 as described above, exposing first flange 149 thereof for mounting to vertical frame member 58. A pair of fasteners (not shown) are inserted through the hole marked “0.000” and the corresponding horizontal hole (marked “0.500”) of the lower pair of holes in first set 153 of holes in first flange 149, and engage a corresponding pair of holes 76 in vertical frame member 58 to secure intermediate horizontal frame member 144 to panel frame 56, with intermediate horizontal frame member 144 located at a desired one inch interval with respect to the surface of floor 52, for example, 12 inches as shown in FIG. 9F.

[0135] In FIG. 9G, intermediate horizontal frame member 144 and first flange 149 of L-shaped bracket 147 are moved upwardly one eighth of an inch from the position shown in FIG. 9F, and a pair of fasteners (not shown) are inserted through the hole marked “0.125” and the corresponding horizontal hole (marked “0.625”) of the upper pair of holes in first set 153 of holes in first flange 149, engaging a corresponding pair of holes 76 in vertical frame member 58 to secure intermediate horizontal frame member 144 to panel frame 56, with intermediate horizontal frame member 144 located at a desired one eighth inch interval with respect to the surface of floor 52, for example, 12.125 inches as shown in FIG. 9G.

[0136] In FIG. 9H, first flange 149 of L-shaped bracket 147 is attached to intermediate horizontal frame member 144 as described above, exposing second flange 151 thereof for mounting to vertical frame member 58. A pair of fasteners (not shown) are inserted through the hole marked “0.250” and the corresponding horizontal hole (marked “0.750”) of the lower pair of holes in second set 157 of holes in second flange 151, engaging a corresponding pair of holes 76 in vertical frame member 58 to secure intermediate horizontal frame member 144 to panel frame 56, with intermediate horizontal frame member 144 located at a desired one quarter inch interval with respect to the surface of floor 52, for example, 12.250 inches as shown in FIG. 9H.

[0137] In FIG. 91, intermediate horizontal frame member 144 and second flange 151 of L-shaped bracket 147 are moved upwardly another one eighth inch from the position shown in FIG. 9H, and a pair of fasteners (not shown) are inserted through the hole marked “0.375” and the corresponding horizontal hole (marked “0.875”) of the upper pair of holes in second set 157 of holes in second flange 151, engaging a corresponding pair of holes 76 in vertical frame member 58 to secure intermediate horizontal frame member 144 to panel frame 56, with intermediate horizontal frame member 144 located at a desired three eighths inch interval with respect to the surface of floor 52, for example, 12.375 inches as shown in FIG. 9I.

[0138] Continuing with the foregoing progression, and as may be seen in FIGS. 9F-9I, the other holes labeled “0.500” and “0.625” in first set of holes 153 in first flange 149 and the other holes labeled “0.750” and “0.875” in second set of holes 157 in second flange 151 may be used to attach intermediate horizontal frame member 144 to panel frame 56 with intermediate horizontal frame member 144 located at any one eighth inch interval with respect to the surface of floor 52. In this manner, the location of intermediate horizontal frame member 144 with respect to the surface of floor 52 may be varied up to one eighth of an inch, based upon the orientation of L-shaped brackets 147 and upon which holes in sets 153 and 157 of first and second flanges 149 and 151, respectively, of L-shaped-brackets 147 are used. Further, as shown in FIGS. 9F-91, mounting tracks 156 are attached to intermediate horizontal frame members 144 as described below, such that mounting tracks 156 may in turn be located at any desired one eighth inch interval with respect to the surface of floor 52.

[0139] Referring to FIGS. 7A and 21, mounting tracks 156 may be connected to horizontal frame members 60 adjacent the upper or lower ends of frame 56, as well as to intermediate horizontal frame members 144, which may be located at any desired vertical height with respect to frame 56, as described above. Mounting tracks 156 are described in detail in U.S. Pat. No. 5,309,686, assigned to the assignee of the present application, the disclosure of which is expressly incorporated herein by reference. Referring to FIG. 21, mounting tracks 156 generally include an extruded metal rectangular channel 158 defined by back wall 160 and upper and lower edges 162, 164, which terminate in upper and lower face surfaces 166 and 168, respectively. Back wall 160 includes V-shaped groove 170, permitting fastener 172 to be centered therein. Referring also to FIG. 7A, fastener 172 is threaded through back wall 160 and into first channel 92 of horizontal or intermediate frame members 60, 144, with the threads of fastener 172 engaging protrusions 96 at the opening of first channel 92 to secure mounting track 156 to horizontal or intermediate frame members 60, 144. Notably, because V-shaped groove 170 of mounting track 156 and first channel 92 of horizontal or intermediate frame members 60, 144 each extend continuously along the long dimensions of same, fasteners may be used to attach mounting track 156 to horizontal or intermediate frame members 60, 144 at any desired horizontal location thereon.

[0140] As described in the above-incorporated U.S. Pat. No. 5,309,686, modular office furniture components, such as work surfaces, cabinets, or shelves, for example, may be attached to mounting tracks 156 at any horizontal location therealong, and, due the variable vertical location of intermediate frame member 144 to which mounting track 156 may be attached, such modular components may therefore be located at virtually any vertical location with respect to frame 56 of panel 44. For example, as shown in FIG. 1, cabinet 174 is mounted to mounting track 156 of a panel 44 at an intermediate level between floor 52 and ceiling 54.

[0141] Additionally, as shown in FIG. 34, mounting tracks 156 of panels 44 of wall panel system 42 may be aligned with similar mounting tracks 156 which are mounted to an existing permanent wall 43 to provide aesthetic continuity between panels 44 of wall panel system 42 and existing permanent walls 43. Mounting tracks 156 may be mounted to permanent walls 43 in the manner described in the above-incorporated U.S. Pat. No. 5,309,686. Specifically, mounting tracks 156 may be mounted to studs 47 of permanent wall 43 using bolts (not shown), or may be mounted to the drywall or other wall material of permanent wall 43 intermediate studs 47 using a bolt and molly anchor assembly (not shown), for example. With further reference to FIGS. 9F-91, intermediate frame member 144 of a panel frame, with mounting track 156 attached thereto, is mounted to the panel frame at a height such that mounting track 156 of the panel frame horizontally aligns with mounting track 156 on permanent wall 43 as shown in FIG. 34, such that mounting track 156 of panel 44 and mounting track 156 of permanent wall 43 are disposed at the same vertical level throughout the office space. The manner in which intermediate frame member 144 and mounting track 156 of a panel frame may be mounted thereto at any selected vertical height, up to an ⅛″ interval, is described above. Advantageously, the alignment of mounting tracks 156 of panels 44 of wall panel system 42 with mounting tracks 156 on existing permanent wall 43 provides aesthetic and functional continuity throughout the office space, for example, by allowing modular office furniture components to be attached at the same vertical height to one or both of mounting tracks 156 of panels 44 of wall panel system 42 and mounting tracks 156 of permanent wall 43.

[0142] Referring to FIGS. 10 and 11, floor track 64 additionally includes slots 176 in central portion 178 thereof intermediate recesses 140 for receipt of U-shaped connecting brackets 180, which are used to connect electrical or data harness assemblies 186 to floor track 64 of frame 56. Tabs 183 of connecting brackets 180 are inserted within slots 176, and connecting brackets 180 are then moved along the longitudinal axis of floor track 64 to capture connecting brackets 180 within narrow portions 182 of slots 176 to secure connecting brackets 180 to floor track 64. Connecting brackets 180 include apertures 184 therein into which fasteners 185 (FIG. 10) may be received to mount harness assembly 186 to floor track 64. In the embodiment shown in FIGS. 10 and 11, fasteners 185 are disposed both through electrical outlet modules 188 and through connecting brackets 180 to connect outlet modules 188 to harness assembly 186 and also to connect harness assembly 186 to connecting brackets 180 of floor track 64.

[0143] Harness assemblies 186 may be, for example, 240 Series, 8 wire UL #183 assemblies, available from Group Dekko Engineering, Pent Div., of Kendalville, Ind., and generally include harness portions 190 which contain electrical wiring and to which electrical outlet modules 188 are attached, and electrical connection ports 192 for connecting wire jumpers (not shown) thereto. Such wire jumpers are used to connect electrical harness assemblies 186 of adjacent panels 44 together to thereby provide electrical service throughout panel system 42. Each panel frame 56 may include one or more harness assemblies 186 centrally mounted to floor track 64 of frame 56 about a vertical axis of symmetry of frame 56, with jumpers of various lengths used to connect the harness assemblies 186 of adjacent panels 44, wherein the length of the jumpers is selected to correspond to the width of the respective panels 44. In addition to electrical wiring and outlets, harness assemblies 186 may additionally include telephone and data wiring and outlets to provide telephone and data service throughout panel system 42.

[0144] Harness assemblies 186 may also be mounted to intermediate horizontal frame members 144 if desired, to provide electrical or data service accessible at any mid-height, vertical location on panel 44 at which intermediate horizontal frame members 144 are disposed. In such an embodiment, intermediate horizontal frame members 144 may be mounted to vertical frame members 58 with harness assemblies 186 aligned with windows 78 in vertical frame members 58, such that jumpers may extend through windows 78 to connect with harness assemblies 186 of adjacent panels 44.

[0145] A second embodiment, illustrating an alternative manner of mounting electrical harness assemblies 186 to floor tracks 0.64, is shown in FIGS. 12A and 12B. Floor track 64 may be provided with slots 177 for receipt of spring legs 224 of spring clips 220 to thereby attach spring clips 220 to floor track 64. Connecting brackets 189 each include aperture 191 for receipt of spring body portions 222 of spring clips 220 therein to removably attach connecting brackets 189 to floor track 64. Connecting brackets 189 are may be formed from pieces of metal bent into a generally U-shape, and additionally include several holes 193 for receipt of fasteners 185 for securing electrical outlet modules 188 and harness portions 190 of harness assemblies 186 thereto in order to attach harness assemblies 186 to floor track 64, similar to the manner described above with regard to FIGS. 10 and 11.

[0146] Adjacent panels 44 a, 44 b (FIG. 15A) may be connected in an end-to-end manner according to a first embodiment, with panel connecting brackets 194, shown in FIGS. 13 and 14, which may comprise a piece of stamped and bent steel, for example. Panel connecting brackets 194 include slot 196 defining first connecting fingers 198 and, on an opposite end thereof, U-shaped slot 200 defining second connecting fingers 202. A building module end-to-end connection 46 between adjacent panels 44 a and 44 b is shown in FIG. 15A, in which a corner post is not used. As shown in FIG. 15A, connecting brackets 194 connect the upper ends of adjacent panels 44 a, 44 b in an end-to-end manner by inserting first connecting fingers 198 within first apertures 204 in jack post plate 100 a of a first panel 44 a, and inserting second connecting fingers 202 within second apertures 206 of jack post plate 100 a of an adjacent panel 44 b, with bolt 210 disposed within U-shaped slot 200. Thereafter, bolt 210 is tightened within first bore 108 of block portion 106 to secure connecting bracket 194 in position by capturing same between the head of bolt 210 and jack post plate 100 a, wherein the engagement of first and second connecting fingers 198, 202 of connecting bracket 194 within first and second apertures 204, 206 of plate 100 a, respectively, prevent separation of the connected panels 44 a, 44 b.

[0147] Panel connecting brackets 194 also connect to plates 100 a of panel support blocks 102A of adjacent panels 44 to secure the lower ends of panels 44 together in the same manner as that described above with respect to the upper ends of panels 44. However, rather than using bolt 210 to lock connecting brackets 194 in position, first nut 116 a of bolt 114 is tightened to secure connecting brackets 194 in position adjacent the lower ends of panels 44.

[0148] Referring still to FIG. 15A, a further panel 44 c may be connected to panels 44 a, 44 b to form a building module T-type connection 48 a using another panel connecting bracket 194 in a similar manner as that described above, in which first connecting fingers 198 of panel connecting bracket 194 are inserted within adjacent third apertures 208 of jack post plates 100 a of panels 44 a, 44 b. After second connecting fingers 202 of connecting bracket 194 are inserted within second apertures 206 of jack post plate 100 a of panel 44 c, bolt 21.0 is tightened to secure connecting bracket 194 in position as described above. A further connecting bracket 194 may be used to connect a fourth panel (not shown) to the above-described building module T-type connection 48 a opposite panel 44 c in the same manner as that described above to form a building module X-type connection between four adjacent panels. Connecting brackets 194 may also be attached in the same manner as that described above to connect the lower ends of panels 44 a-c together.

[0149] As shown in FIG. 15B, corner post 212 may be used to connect adjacent panels 44 a, 44 b together in a furniture module L-type connection 50 b in a similar manner as described above, in which the connecting fingers of connecting brackets 194 engage apertures 216 in cover plate 214 of corner post 212. Similarly, additional panels may be connected to corner post 212 using additional connecting brackets 194 to form a furniture module T-type connection 48 b or a furniture module X-type connection therebetween. Advantageously, adjacent panels 44 may be connected to one another in and end-to-end manner, or to form building and furniture module L-type connections 50 a, 50 b, building and furniture module T-type connections 48 a, 48 b, or furniture and building module X-type connections using the same panel connecting brackets 194, which greatly reduces the total number of components of floor-to-ceiling wall panel system 42.

[0150] Referring to FIG. 15C, an end-to-end panel connection according to a second embodiment is shown, in which adjacent panels 44 a, 44 b are connected using cam locks 181. Cam locks 181 include circular plate 183 having hexagonal nut head 185 on one side thereof and a pair of cam lugs 187 protruding from an opposite side thereof. Referring to FIGS. 15C and 15D, plates 100 b of adjacent panels 44 a, 44 b are abutted against one another, and cam lugs 187 of cam locks 181 are inserted into wide portions 105 of adjacent cam slots 101, as shown in FIG. 15C. Cam locks 181 are then turned by engaging a tool (not shown) with nut head 185 of cam lock 181 and rotating same approximately one quarter of a full turn, as shown by the arrow in FIG. 15D, such that cam lugs 187 engage narrow portions 107 of cam slots 101. The engagement of cam lugs 187 into narrow portions 107 of cam slots 101 is a close-fitting engagement which produces a tactile feel to the installer, thereby indicating to the installer that cam lugs 187 have been properly engaged with narrow portions 107 of cam slots 101 to lock adjacent panels 44 a, 44 b together, as shown in FIG. 15D. The bottom ends of adjacent panels 44 a, 44 b are connected to one another in the same manner as described above.

[0151] A building module X-type connection is shown in FIG. 15E, which is formed by connecting two additional panels 44 c, 44 d to the end-to-end building module connection shown in FIGS. 15C and 15D and described above. As shown in FIG. 15E, when panels 44 a, 44 b are connected together in an end-to-end connection, half cam slots 103 of adjacent plates 100 b thereof combine to form full cam slots 101. Subsequently, adjacent panels 44 c, 44 d may be connected by abutting plates 100 b of same in a perpendicular relationship to the plates 100 b of panels 44 a, 44 b, and connecting the foregoing together using cam locks 181 as described above, wherein cam lugs 187 of cam locks 181 engage full cam slots 101 of plates 100 b of panels 44 c, 44 d, and also engage the combined half cam slots 103 of plates 100 b of panels 44 a, 44 b. From FIG. 15E, one may see that by connecting only one panel 44 c to the building module end-to-end connection of panels 44 a, 44 b, a building module T-type connection 48 a may be formed.

[0152] Referring to FIG. 15F, an L-type building module connection 50 a is shown, wherein adjacent panels 44 a, 44 c are each connected to finished end unit 195.

Thereafter, additional panels 44 c-d may be connected to corner post unit 213 using additional cam locks 181. From FIG. 15H, one may see that an L-type furniture module connection 50 b may be made by connecting two panels 44 a, 44 b to corner post unit 213, and a T-type furniture module connection 48 b may be made by connecting three panels 44 a-c to corner post unit 213.

[0156] Spring clips 220, shown in FIG. 16, are used to attach various components of floor-to-ceiling panel system 42 to frames 56 of panels 44, as described below. Spring clips 220 may be formed from stamped and bent pieces of spring steel, for example. Spring clips 220 are somewhat horseshoe-shaped in overall appearance, and include central, arched spring body portion 222 from which extend a pair of spring legs 224. As shown in FIGS. 9, 15A-15B, 18, 20-21, and 23-24, spring clips 220 may be connected to vertical frame members 58 by engaging spring legs 224 thereof within horizontally adjacent pairs of slots 80 in sub-frame members 68 of vertical frame members 58. Additionally, spring clips 220 may be attached at any horizontal location along horizontal or intermediate frame members 60, 144 in any of the three vertically spaced positions aligned with first and second channels 92, 94 thereof (FIG. 7A), wherein spring legs 224 of spring clips 220 engage spaced pairs of protrusions 96 at the openings of first and second channels 92, 94 of horizontal or intermediate frame members 60.

[0157] Opaque panel skins 226, shown in FIGS. 17A and B, may generally include a piece of sheet metal or plastic with panel face 228 having the edge regions thereof bent or formed to define frame portion 230. Core 231 is received within frame portion 230, and is attached thereto in a suitable manner such as by adhesive, for example. Core 230 may be formed from a lightweight material such as honeycomb cardboard. Typically, opaque panel skins 226 are covered with a surface finish, such as paint, wood veneer, or an upholstery material such as fabric or vinyl. Alternatively, opaque panel skins 226 may include only a plastic or metal frame portion 230 which encloses a panel portion made from solid wood, a veneered manufactured wood material, molded plastic, upholstery, fabric, or any other suitable material. Frame portion 230 includes apertures 232 which are adapted to receive spring body portions 222 of spring clips 220 therein, as discussed below. Light and sound seals 234, further described below, are attached along the rear sides of the vertical edges of frame portions 230 by adhesive, for example.

[0158] Referring to FIGS. 18A and 18B, to detachably mount opaque panel skins 226 to panel frame 56, spring clips 220 may be first attached to vertical and/or horizontal frame members 58, 60, followed by pressing spring body portions 222 of spring clips 220 within apertures 232 in frame portion 230 of opaque panel skins 226. Specifically, spring body portions 222 deform when pressed through the edges of apertures 232 and then spring back to their original shape with an audible clicking sound after passing therethrough to secure opaque panel skins 226 to frame 56. Opaque panel skins 226 may be removed from panel frame 56 by pulling same away from panel flame 56, such that spring body portions 222 of spring clips 220 disengage from apertures 232 in frame portion 230 of opaque panel skin 226. An exemplary panel 42 having an opaque panel skin 226 attached thereto is shown in FIG. 18C.

[0159] Opaque panel skins 226 may be sized as shown in FIG. 26 such that, when adjacent panels are attached to one another in a side-to-side relationship, the ends of opaque panel skins 226 may directly abut one another to provide a continuous vertical wall surface. Alternatively, as also shown in FIG. 26, opaque panel skins 226 may be sized such that a vertical gap is left therebewteen when adjacent panels are attached to one another in a side-to-side relationship. In either of the foregoing arrangements, flexible light and sound seals 234 of panel skins 226 deform upon engagement with one another, as shown in FIGS. 15A and 26, or upon engagement with adjacent structures such as corner post 212, as shown in FIG. 15B, to provide a seal which blocks the transmission of light and sound through the connective interface of panels 44. Light and sound seals 234 may also be deformed inwardly to allow access to slots 80 of vertical frame members 58 for attachment of modular furniture components thereto.

[0160] In addition to opaque panel skins 226, panels 44 may include window panels 236 (FIGS. 19, 22A), which generally include window frame 238 attached to panel frame 56 by first or second horizontal window casings 240 a (FIG. 7E), 240 b (FIG. 7F) and vertical window casings 242 (FIG. 7H), as described below.
